Abstract
Fourteen strains of 9 wild species, 10 imported cultivars (O. sativa) and 3 Japanese cultivars were tested for resistance to P. oryzae strains P-2 and 54-04 by spraying and by inoculation. Among the wild strains 0. australiensis was very susceptible to both fungal strains. 0. officinalis (?), O. eichingeri (?), O. latifolia and O. breviligulata (?) exhibited resistance to P-2 when sprayed and resistance or moderate susceptibility when inoculated; they were resistant to 54-04 when inoculated.
